The aircraft, which was coupled to the autopilot when these oscillations occurred, was not able to provide a stabilized approach from the final approach fix through the decision altitude or the minimum descent altitude. These intermittent oscillations occur during the landing phase of a flight, at an altitude of 500 feet or less above ground level, and result in higher single-pilot workload. After an investigation, Eurocopter determined that these oscillations were caused by software in the automated flight control system (AFCS) that does not adequately filter the electronic ‘‘noise’’ from the U.S. ILS and LOC signals. This behavior of the autopilot was not experienced by aircraft operating in European airspace. An additional FAA flight test of an EC155B1 with unmodified AFCS software coupled to various ILS signals confirmed the oscillations, and that they can roll the helicopter up to +/¥15 degrees. Eurocopter is developing a software modification that will update the filtering algorithms for U.S. category 1 ILS and LOC signals. Until this update is approved by the European Aviation Safety Agency and validated by the FAA, we have determined that single pilot IFR operations constitute an unsafe condition for this model helicopter. VerDate Mar<15>2010 14:46 Jul 26, 2012 Jkt 226001 FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. We are issuing this AD because we evaluated all the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other helicopters of the same type design. AD Requirements This AD requires, before further flight, changing the minimum flight crew requirements for IFR operations from one pilot to two by revising the rotorcraft flight manual (RFM) Operating Limitations section. Interim Action We consider this AD to be an interim action. The design approval holder is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance We estimate that this AD will affect six helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Revising the RFM will require about .25 hour at an average labor rate of $85 per work-hour, for a total cost per helicopter of about $22 and a total cost to U.S operator fleet of $132. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the required corrective actions must be accomplished before further flight. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in less than 30 days. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 44119 detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed, I certify that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

On May 9, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish controlled airspace at Roundup, MT (77 FR 27148). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. The FAA received three comments, all from the National Business Aviation Association (NBAA). The NBAA comments recommended that the FAA lower some of the adjacent Class E airspace, which is beyond the TAAs, down to 1,200 feet above the surface to accommodate orderly en route descent into the respective TAA because the NBAA feels that aircraft will not have enough airspace to access the TAAs. The airspace in question includes the following areas where Class E begins at 14,500 feet MSL: The large area to the north, the two smaller areas to the west, and the small area to the east.

Finally, the commenter points out that extending the Class E 1,200-foot area would provide relief to Salt Lake City Air Route Traffic Control Center (ARTCC). The FAA believes that lowering this airspace is outside the scope of this rulemaking at this time, and would not serve the immediate purpose of establishing the airspace necessary for the safety of aircraft within the Roundup, MT, airport area. Class E airspace designations are published in paragraph 6005, of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order. The Rule This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class E airspace, extending upward from 700 feet above the surface, at Roundup Airport, to accommodate IFR aircraft executing new RNAV (GPS) standard instrument approach procedures at the airport. This action is necessary for the safety and management of IFR operations. The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation because the anticipated impact is minimal. This rule will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act because this is a routine matter that will only affect air traffic procedures and air navigation. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of E:\FR\FM\27JYR1.SGM 27JYR1

Discussion

    During a flight test of a Model EC155B1 helicopter, intermittent 
uncommanded roll oscillations were discovered during coupled instrument 
landing system (ILS) and localizer (LOC) approaches. The aircraft, 
which was coupled to the autopilot when these oscillations occurred, 
was not able to provide a stabilized approach from the final approach 
fix through the decision altitude or the minimum descent altitude. 
These intermittent oscillations occur during the landing phase of a 
flight, at an altitude of 500 feet or less above ground level, and 
result in higher single-pilot workload.
    After an investigation, Eurocopter determined that these 
oscillations were caused by software in the automated flight control 
system (AFCS) that does not adequately filter the electronic ``noise'' 
from the U.S. ILS and LOC signals. This behavior of the autopilot was 
not experienced by aircraft operating in European airspace. An 
additional FAA flight test of an EC155B1 with unmodified AFCS software 
coupled to various ILS signals confirmed the oscillations, and that 
they can roll the helicopter up to +/-15 degrees.
    Eurocopter is developing a software modification that will update 
the filtering algorithms for U.S. category 1 ILS and LOC signals. Until 
this update is approved by the European Aviation Safety Agency and 
validated by the FAA, we have determined that single pilot IFR 
operations constitute an unsafe condition for this model helicopter.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. We are 
issuing this AD because we evaluated all the relevant information and 
determined that an unsafe condition exists and is likely to exist or 
develop on other helicopters of the same type design.

AD Requirements

    This AD requires, before further flight, changing the minimum 
flight crew requirements for IFR operations from one pilot to two by 
revising the rotorcraft flight manual (RFM) Operating Limitations 
section.

Interim Action

    We consider this AD to be an interim action. The design approval 
holder is currently developing a modification that will address the 
unsafe condition identified in this AD. Once this modification is 
developed, approved, and available, we might consider additional 
rulemaking.

Costs of Compliance

    We estimate that this AD will affect six helicopters of U.S. 
Registry. We estimate that operators may incur the following costs in 
order to comply with this AD. Revising the RFM will require about .25 
hour at an average labor rate of $85 per work-hour, for a total cost 
per helicopter of about $22 and a total cost to U.S operator fleet of 
$132.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we find that 
the risk to the flying public justifies waiving notice and comment 
prior to the adoption of this rule because the required corrective 
actions must be accomplished before further flight.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
